The Right and Wrong Way to Tack Weld

Another title to this post would be: “The effect that heat has on metal”. I tried to explain two different things on this video. 1. The correct placement of tacks.  2. The effect heat has on steel.

After the video was shot I noticed just how far the end of the flat steel pulled up off the table after I welded the tube that was tacked correctly. Since the tube was tacked on the opposite side of the weld, it (the heat) used the tube as a pry bar to bend the flat iron up in the air. Check out the picture below to see how flat the flat iron is directly under the tube. It only bent where the weld was put. This is just another example of how heat can manipulate steel.
